Title: Improvements in or relating to the manufacture of hollow bodies, such as bottles, from paper or the like
IPC: B31B50/00
Filed: 1934-11-26
Abstract: 435,898. Shaping paper tubes. BERLINER MASCHINENBAU AKT.- GES. VORM. L. SCHWARTZKOPFF, 23, Chausseestrasse, Berlin. Nov. 26, 1934, No. 33947. Convention date, Nov. 25, 1933. [Class 99 (ii)] In the manufacture of bottles &c. from paper tubes, each tube 3 is first conically tapered at one end by. folding and is then inserted by a pusher 2 into a pressing mould 1 where the folded end is permanently shaped, and also preferably provided at its extremity with a neck, by the head 5 of a plunger 4. The head 5 is introduced into the restricted end or neck 10 of the mould until it is located in a conically, widened portion 9 thereof, whereupon the folded end of the tube is inserted into the mould, and when a short length of the tube projects into the neck 10 the head is withdrawn at a speed equal to that at which the tube is being inserted. A spring-pressed sleeve 6 is provided on the plunger 4 for limiting the movement of the tube into the mould.

Title: Arrangement for centrally introducing cartridges into the cartridge chamber of automatic fire-arms
IPC: F41A9/42
Filed: 1947-12-23
Abstract: 639,748. Automatic firearms. ZBROJOVKA BRNO, NARODNI PODNIK. Dec. 23, 1947, No. 33980. Convention date, March 8, 1943. [Class 92 (ii)] An automatic firearm has a transversely sliding breech-block 4 whose movements are controlled by a longitudinally movable carrier 5, and a sliding support 11 for a cartridge feeder and cartridge case extractor arranged between the breech-block and its carrier, stopping means being provided for limiting the sliding movement of the support 11 along the carrier to the period of transverse breechblock displacement thus permitting the support to stand still during that period. In the construction shown the breech-block carrier 5 carries a spring-controlled pivoted arm 14 having a nose 19 which by contacting a fixed surface 20 of the firearm, depresses the arm, as shown, to a position in which a shoulder 17 of the arm is released from engagement with a groove 18 in the member 11. The member 11 carries an extractor 22 and a lever 27 controlled respectively by springs 24, 28, and both mounted on a pin 23. When the parts recoil on firing a shot, grooves 7 in the carrier 5 act on rollers 6 to raise the breech-block 4, the member 11 remaining stationary during this operation. At the point where the breechblock is raised the nose 19 slips off surface 20 to allow shoulder 17 to enter the groove 18, and a shoulder 13 at the end of a groove 12 in the carrier, along which groove the member 11 slides, engages the member 11 and takes it to the rear. The spent case 9 is thus withdrawn from the chamber 9 by the extractor 22 being aided by the lever 27 which was allowed to rise by the lifting of the breech-block. A projection 25 on the extractor is later engaged by a surface 26 to release the spent case when it is reintroduced into the cartridge belt. A spring 8 returns the carrier to the forward position, and a new round is taken by the parts 22, 27 into the chamber 3. When the round is inserted the nose 19 is depressed by the surface 20 to remove the shoulder 17 from the groove 18, whereby the member 11 remains stationary as the carrier completes its forward movement. In a modification the extractor 22 has a rearward extension which engages a fixed surface to cause the pivotal movement as above described.

Abstract: 467,423. Air compressors. SULZER FRERES SOC. ANON. Dec. 16, 1935, No. 34825. Convention date, Dec. 20, 1934. [Class 8 (i)] [Also in Group XXVI] In a power plant made up of a " free stroke " reciprocating piston compressor actuated by internal-combustion cylinders and delivering gas under pressure to a consumer (e.g. a turbine), the scavenging air is wholly or in part supplied by an auxiliary turbo-compressor the supply to which is controlled by the governor of the main turbine. In Fig. 1, a cylinder 1 contains pistons 2, 3, working on a " free-stroke " principle, synchronized by links 4, 5, 6. One end of each piston reciprocates in the cylinder 7 and the other end in an air compression cylinder 8, 9. Air is supplied to these cylinders by the blower 32 through pipe 10, where it is compressed and passed through pipe 15 and inlet ports 17 into cylinder 7. It then forces the waste products and excess air through ports 20 into delivery pipe 22 to main turbine 24 which may exhaust into a heat-exchanger or elsewhere. A throttle valve 34, controlled by the main governor 29 is fitted in a branch pipe 23 which delivers the gases to an auxiliary turbine 30 which may exhaust to atmosphere or to an intermediate stage of the main turbine. The throttle valve 34 of the auxiliary turbine is so controlled that an increase in load opens it and causes turbine 30 to speed up and deliver more air at higher pressure to cylinder 8, 9 and consequently to cylinder 7. An increase in fuel supply to the cylinder 1 then follows with a resulting increase in gas supply to pipe 22. A branch pipe 35 with non- return valve 36 is fitted to pipe 10, so that when the load on main turbine is low and auxiliary turbine shut down, air may be drawn into cylinders 8, 9. Fig. 3 shows the means adopted to allow the governor to function when valve 41 is on its seat.
